Inquiry regarding scar management after squeezing acne

I couldn't resist squeezing my pimples, and now I'm worried because they leave red marks and dark spots. I have patches on right now, but what should I apply to prevent scarring? I'm not sure if cica cream or vitamin serum would be effective, or if I should get treatment at a dermatologist's office.

Since I just squeezed it out, I feel like I need to use a gentle product, but I'm also wondering if it's okay to apply something with whitening ingredients right now. Please share any tips for quickly calming down the marks, or any skincare routines you've personally seen results from.

I would appreciate it if you could share home care methods that I can do at home, rather than laser treatments at a dermatology clinic. Please give me some help from those who are good at managing scars.
